76144-22-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 76144-22-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,6,1,4 and 4 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 76144-22:
(7*7)+(6*6)+(5*1)+(4*4)+(3*4)+(2*2)+(1*2)=124
124 % 10 = 4
So 76144-22-4 is a valid CAS Registry Number.
